Gu Nan seemed calm on the surface, but in fact, her whole mind was in a trance. In fact, she knew very well in her heart that the rumors related to the Yanfeng royal family that could be circulated in various channels were true. As the saying goes, there is no wind and no waves, and those who dare to pass on this kind of news will definitely not chase after the wind and shadows casually.

He's going to get married after all, and he won't be able to marry me after all...... After getting the answer, Gu Nan, who was in a trance, even forgot to say goodbye to the royal family, and turned around and left without waiting for Zhao Hongxing to get in the car and set off first, and when she returned to the private room on the fourth floor, she didn't find that there were two people missing in the room.

Zhao Hongxing watched Gu Nan disappear into Chenglou and prepared to get in the car and go back to the palace.

Alas, poor girl, it is the cruelest thing to be destined to have nothing to do with her sweetheart.

"Your Royal Highness the Sixth Prince, please wait a minute!" Before Zhao Hongxing could lift his feet when he got into the car, he heard someone shouting behind him.

"His Royal Highness the Sixth Prince?"

"The six princes of the royal family?"

"I haven't seen the living Six Princes yet!"

The shout of "......" caused a commotion in the surroundings.

In order to avoid extravagance and waste - the main thing is to spend their own money and not be too lavish - the people of the Yanfeng royal family rarely pay attention to pomp and circumstance when they go out, after all, when they pay attention to pomp, they have to spend their own money, and there is no need to spend money on non-special occasions.

Zhao Hongxing went out today, in addition to the coachman and the two guards, even Shangle Aya and Hongyi and himself, a total of six people.

These six people were not so conspicuous at the door of Chenglou, but suddenly someone shouted at them, and they were noticed by the crowd who loved to join in the fun.

At this time, there was a shouting defense line, and two people, one fat and one thin, trotted towards Zhao Hongxing.

"Who is shouting so loudly in front of His Highness!" Hongyi stepped forward to block in front of Zhao Hongxing, and scolded the two people.

"Your Royal Highness the Sixth Prince, I'm very sorry. When he came closer, the thin man pulled the fat man and bowed incessantly.

"What's the matter?" Zhao Hongxing saw that the people around him began to gather around, ready to make a long story short with these two people.

"Your Highness, I am from the southwest, and my family has been developing some secret supplies for generations. The fat man bowed down and said, "Not long ago, there was a great discovery in my home, but I must not make a noise about it, so I tried my best to tell the royal family about it secretly." There are many offenses in a hurry, and I forgive your Highness. ”

Developing some kind of secret product? Hey, could it not be a secret product like "Qi X Hehuan San"? Looking at this fat and thin duo, Zhao Hongxing really couldn't guess what they were developing.

"In a hurry?" Zhao Hongxing continued to ask briefly.

"It's about the safety of the family and the country!" the fat man said urgently.

This...... Is it so serious? Zhao Hongxing summed it up in his heart. Even if these two people came to the capital after trekking through mountains and rivers, and spent a lot of financial resources and minds to meet the members of the royal family, it may be really something.

That's it, in case something really big is delayed by yourself again.

Zhao Hongxing called a guard who came out with him, whispered the name of a teahouse to the guard, and then said to the fat and thin duo: "Follow him, I will wait for you in a place suitable for talking." ”

Before being surrounded by the onlookers, Zhao Hongxing hurriedly took Le Aya into the carriage and left Chenglou.

Riding in a carriage, Zhao Hongxing came to a teahouse on the side of the canal. This teahouse is not the property of the royal family, but fortunately, it is very suitable for discussing things. This teahouse has no loose tables, only private rooms, and if you want to drink tea in the private room, you must spend a specified amount of silver, and the consumption is definitely not a small amount.

Fortunately, it is not the one who does not spend money on everything. Although the consumption of this tea house is high, the environment and the quality of things are indeed excellent. The tea in this teahouse is a very high-end and rare famous tea, but Zhao Hongxing can't taste tea, he thinks that no matter how fragrant it smells, it will be a bitter taste in his mouth. However, the dim sum sold in this teahouse is also very good, and the dim sum chef in the teahouse makes something that tastes even better than the taste in the palace.

At this moment, Zhao Hongxing, who first came to the teahouse to find a room to sit down, ordered a lot of food and tea according to the regulations. Although the shopkeeper in this store knew Zhao Hongxing, he didn't give a discount at all on the price of entering the private room, but just packed some best-selling snacks and sent them to his carriage, which was considered a gift.

These two guys had better tell me something more useful. When Zhao Hongxing asked Hongyi to pay for the money, he said silently in his heart.

It just so happens that this teahouse is also close to the canal, if Zhao Hongxing thinks that what this fat and thin combination says is not worth the money for this meal, then he will throw it into the river for these two people with his own hands.

Le Aya sat in the room, happily eating the pastries on the table, and from time to time she took two sips of tea. These things don't cost her money anyway, and they don't eat for nothing.

In the middle of the night, the fat and thin combination of people was brought.

As soon as he entered the house, before he could sit down, the fat man couldn't wait to speak.

"Your Highness, please be sure to tell His Majesty the Emperor about today's events. The fat man said with some pleading.

"Qi Gongzi, you sit down first, the matter has not been clarified to His Royal Highness the Sixth Prince, why do you want to talk about this first?" On the side, the thin man grabbed the fat man and asked him to sit down quickly, then looked at Zhao Hongxing and said with a smile: "Your Highness the Sixth Prince, please allow me to introduce myself." ”

As he spoke, the thin man first pointed to the fat man named Qi Gongzi, "This is the eldest son of a technical family in the southwest, Qi Huan." ”

After speaking, he pointed to himself again, "Down here is a friend of Qi Gongzi, named Liang Yu." ”

Zhao Hongxing is a little unfamiliar with this term, "technology" in Yanfeng almost represents the meaning of "scientific research", and there is a special "technical hall" in the Hanlin Academy, which is used to study various new technologies, which belongs to a department that contributes to the future of the country.

But Zhao Hongxing, a "family of technical experts", has only heard of it and has never seen it. After all, in order to conduct research, in addition to the need for knowledge, it is also essential to have sufficient funding. The Girido can use the huge budget allocated by the treasury to do all kinds of science, even if there is no success in thirty or fifty years, Yan Feng will always use the money to "raise" these people. But if it is replaced by something that ordinary people can not implement, and it is not known when it will pay off if it has to invest a huge amount of money in an unknown time, this family has to do what to do and how many families have to do it, so that they can afford such a deficit project.

Seeing that Zhao Hongxing didn't seem to know what they were doing, the thin man named Liang Yu began to explain.

"The Qi family in the southwest where the prince of Qi is located is ostensibly a merchant doing business, but in fact it is a family that has received the secret edict of the royal family and studied some things secretly for the state. Liang Yu said here, and Qi Huan nodded vigorously.

"Moreover, all the funds used by our Qi family for research are secretly allocated by the royal family. Qi Huan added.

Oh, that's bull X. Zhao Hongxing raised his eyebrows and became curious, what kind of secret research is this, you have to find a family so secretly and secretly give money to study?

Kicking out of his mind the cluttered thoughts such as "half a step with a smile", Zhao Hongxing asked, "Then what are you studying?"

"Thunderfire. Qi Huan replied with a little pride.

But Zhao Hongxing was not satisfied with this answer.

Thunder fire is gunpowder, and the gunpowder technology in this world is similar to the ancient black powder technology, which is a proportional mixture of saltpeter and plant ash. As for the power, that is, it can be used to make a cannon fight and listen to the sound, and a large bucket can be used to blast mountains and stones.

Zhao Hongxing, who is not very interested in hot weapons, has not studied the problem of gunpowder production much, and this thing was contraband in his previous life, so he didn't think about reforming the "thunder fire" and creating more powerful weapons to rule the world or something.

I'm not here to farm, I'm here to enjoy life!" Zhao Hongxing emphasized again in his heart.

To get back to the point, Zhao Hongxing thinks so, before the steel manufacturing and lathe industry has not developed, and it is still impossible to manufacture durable and high-precision "hot weapons", the so-called "thunder fire" is a scum that can only be set off a firecracker and listen to the sound, without any military value.

"What, is there something wrong with Lei Huo's research?" Zhao Hongxing asked casually.

"There's not something wrong, Your Highness. Qi Huan said with some pride: "We have developed a new type of thunder fire!"

"Huh?" Zhao Hongxing was puzzled for a moment, and said in his heart, is he going to witness the turning point in the development of weapons in this world?

Next, Qi Huan briefly explained to Zhao Hongxing the principle of making the new thunder fire, as well as its advantages and disadvantages, as well as its general power.

And Qi Huan's explanation, Zhao Hongxing also began to be surprised.

This new type of thunderfire sounds very much like TNT, which is yellow explosives. In particular, the raw materials are exactly the same in terms of toxicity and explosive power. If it wasn't for the direct detonation with an open flame, Zhao Hongxing was still wondering how people in this world could make detonators.

Compared with ordinary black powder, this new type of thunder fire, which is very similar to TNT in power, must be much more useful, but since the Qi family is developing thunder fire for the country, after such a major progress, why don't they report it directly, but instead come to a prince to talk about it?

Zhao Hongxing directly expressed his doubts, but he didn't expect Qi Huan to directly show an expression of wanting to cry without tears, and Liang Yu also had a wry smile on his face.

Then, Liang Yu explained the reason to Zhao Hongxing.

The Qi family lived in a relatively desolate town in the southwest, and settled in such a sparsely populated place not because of poor money, but for the convenience of studying thunder and fire and secrecy.

Thunderfire, like black powder, is a relatively unstable explosive, and can be ignited at a higher temperature. In this place where neighbors can be far apart, the Qi family can rest assured that they can conduct research, and they don't have to worry about accidentally blowing themselves up and implicating others at the same time.

After nearly a hundred years of disdainful efforts by the Qi family, with the addition of Qi Huan, a person who has been interested in "explosions" since childhood, he forgot to sleep and eat, and really developed the "TNT" version of Thunder Fire. On the day of success, the whole Qi family was boiling, and with this research alone, they could completely leave the desolate land in the northwest and even live in the capital.

Liang Yu is the son of a local magistrate and is good friends with Qi Huan. Qi Huan happily told Liang Yu on that day that their family had done a big thing and could go back to the capital on an errand.

Although Liang Yu didn't know what the Qi family was doing, he was still happy that his good friend could move high, and the two had a happy drink together that day.

But what Liang Yu didn't expect was that in the turn of the day, Qi Huan came to him again with a very bad face.

This time, Qi Huan not only explained to Liang Yu what their family was doing, but also said a very strange thing that had just happened.

The head of the Qi family, Qi Huan's father, Old Man Qi, told him that the formula of the new thunder fire was not going to be handed over to the state, but to be bought by a "businessman" who came to the door. The price offered by the other party is enough for their ancestors to eat for four or five generations.

Old Man Qi's unconventional operation made Qi Huan suspicious, and repeatedly asked who this guy was, what he was doing, and where he was now. However, Old Man Qi was like eating a scale, not only did he not answer any questions, but he also forced Qi Huan to ask what the recipe for the new thunder fire was.

In order to get out, Qi Huan made up a recipe and handed it to Old Man Qi, and then hurriedly ran over to discuss with Liang Yu, who was an official at home.

Liang Yu thought about it, this thing is really not good. According to Qi Huan, the Qi family has been secretly studying here for many years, and no one has ever come to look for them during this period. On the day of the success of the new thunder fire, some people came out to buy the child at a high price. No matter who this person was, and no matter how he knew that the Qi family's new Thunder Fire research was successful, just because the use of the Thunder Fire Recipe he secretly bought was still unknown, Liang Yu felt that he couldn't let that guy succeed.

made a decision immediately, Liang Yu did not alarm his family, but used his own connections to set up a line in the capital, and set off with Qi Huan on the same day, and rushed to the capital as soon as possible.

From the time they arrived in the capital to meet Zhao Hongxing today, it has been almost half a month.

If things are really like what the fat and thin second group said, Zhao Hongxing feels that he must pay attention to it. Judging by the experience of various international news that he has read in his previous life, who likes to use explosives to do things the most?

Answer: Terrorists.

These guys like to bury explosives near the target with a secret poke, and then sneak to find an opportunity to detonate it, and after the loud "boom!", any target will be shattered without much effort.

According to this line of thinking, this matter is indeed a matter of national security, and Zhao Hongxing can now think of at least two places that can become "terrorist" targets with a high probability.

One, is the valley wall of the north.

One, it was the prince's wedding scene a few months later.

Thinking of this, Zhao Hongxing broke out in a cold sweat, he was a little glad that he learned about these things from these two people today.

The northern city wall is far away from him, and whether it is blown up or not is not within the scope of his consideration, but Zhao Hongming's wedding scene is different, the entire Yanfeng royal family is going to participate, if this is really buried by someone secretly, if the luck is not good, maybe the Yanfeng royal family will be served in a pot if he is connected again.

"Let's go. Zhao Hongxing didn't talk nonsense, just stood up and left.

Seeing that Zhao Hongxing was leaving, Le Aya looked at the pastries that had not yet been eaten with some reluctance. Seeing Le Aya's reluctant eyes, Hongyi told the servants in the teahouse outside very "intimately" to wrap the pastries on the table again.

"Where are you going?" Seeing that Zhao Hongxing suddenly stood up and said that he was leaving, Qi Huan also asked stupidly, and Liang Yu covered his face speechlessly.

"Where else can I go?" Zhao Hongxing pulled Qi Huan up with his hand.

"I'm going to take you to meet His Majesty the Emperor of Yanfeng quickly!"
